/b all whom t may concern.'

hBe it known that I, NIELs B. JANSSEN, a citizen of the United States,residing at Kansas City, in the county of Jackson and State of Missouri,have invented certain new and useful Improvements inV Conveying andCleaning Tables; and I do declare the following tobe a full, clear, andeXact description of the invention, such as will enable others skilledin the art to which it appertains to'makc and use the same, referencebeing had to the accompanying drawings, and to the lett-ers and figuresof reference marked thereon, which form a part of this specification.

My invention relates to conveying and cleaning tables, and moreparticularly to a table for facilitating the cleaning, and grading ofcelery or the like, the principal object ofthe invention being toprovide a table of this character comprising movable sections whereonthe celery is assorted, cleaned and graded, and which may beinterchanged between workmen who do the separate phases of the worlg sothat the work'is greatly facilitated and accomplished without confusionamong the workers and particularly without bruising or damaging theplants. Y y

A further object,V of the invention is to provide simple and easilyoperated means or interchanging the sections or tablesbetween theworkmen.

In accomplishing these objects I have provided improved details ofstructure, the preferred forms of which are illustrated in theaccompanying drawings, whereinz` liigure I is a perspective view of acleaning and assorting table constructed according to my invention.

CONVEYING AND CLEANING TABLE. i

Patented Jan., 15, 1913.

' Application filed ctober 30, 1916. Serial No. 128,431.

Referring more in detail to the drawings z- 1 designates a cleaningandgrading table constructed according to my invention, comprising a frame2, which may be made in lengths to accommodate a desired number ofworkmen, and having opposite side members 3h3", ends M', and supportinglegs Mounted within the frame between the sides 33, and slightly belowthe top level thereof, are tables 6 6', each of which is of'`approximately one-half the length of the frame 2, and is removablymounted so that the tables may be interchanged as the work progresses.

Attached to the under side of each of the tables by journals 7 are axles8 carrying rollers 9, whereby the tables are supported on tracks 10`10that are carried by and project inwardly from the sides of and eX- tendthroughout the length of the frame.

In order that the tables may be inter changed, the track 10, whichcomprises rails 11-11 and the tie rods 12, is pivotally mounted adjacentits outer end on brackets 13 that are attached to the side frame members3--3 and is supported at its free end by the cross bar 14 of a crank 15,comprising side arms 16-16 and outturned bearing portions 17-17 ed inthe side beams 3-3, the crank being provided, externally of the frameand at one side thereof, with a lever 18 whereby the crank 15 may bemoved to raise the free end of the track 10 and support the sameinhorizontal position and in coextension with the track 10', or to lowerthe free end to a level with sub-tracks 19-19 that are supported in theframe below the track 10.

In order to retain the track 1() normally in horizontal position, Iprovide a support 20 for the lever 18, which is attached to the loweredge of the side rail 3, and so form the crank bar that when the leveris seated on the support 20 the cross bar 14 on which the track rests ispositioned slightly back of the pivotal point of the crank, so that inlowering the track, the bar 14. must be moved back over the dead centerposltion.

The track 19, which is located below the track 10',` comprises spacedrails 21--21 that are `ioined by the end tie rods 22-22, `and when innormal position rests on cross which are pivotally mountbars 2(323 thatextend transversely between the side frames 3-3, and is acontinuationoi? theV track rails 179. which lare V pivotally mounted, and sidearms`27-i-27/ which are [turned laterally at theirends to form 1bearingportions 2S- 2'S which are pivotally mounted 'in the sides "3-3 g saidcranks being provided `at theexterior of the frame with levers 294429that are `pivkotallv Aconnected at their ends a linkBO.

Also pivotallv Connected with 'thel lever 29 is a link `31 which extendsto a lever32,pivolall)`7- n'iounted on the tramo side 3, so that bymoving the lever. 82, the c'ank levers will be rocked on their pivotalmountingl to raise the track 19 lioinlits supports to a positionsubstantially level with the track .10.

The track 10 comprises the side rails 10 preteably of angle ironconstruction and each hingedly mounted on the `fr 'amesides 3&3",so'that the. rails may lie in position to support the tables 6- 6 ormaybe tilted outwardly on their ,hinged mounts topermit the passage of atable, that may be supported onv ,the track 19 therebetween when' thelatter 'is raised by operationof the leyer 32.

In the present'devicel I prefer to cutaway a portion of the front frame3 above'the level of the table G to permit the graded product to'be moreeasily removed from the Vtables after it hasbeen washed. 1 also preferto form the ltables of spaced slats so that water or dirt removed fromtheplants may fall therebetween to lbeneath'theta-ble, in order that theplants may be kept Jfree Jfrom dii-t.

Assuming the parts to be soconstructed, in` using the device,V thetablesG'--G" are raised to position on` the tracks 10--10. The uncleanedIcelery vis iirst placed on'the table G 4where the roots and leaves maybe removed andthe plantswaslied. "The table (3 Vis thenmoved alongthewtrack '10 onto the'track 1'() tothe position previously oc-'cupiedby the table ,6 which in themeantime has been moved to thetrack'19.

To lower the table 6 from the track 10 to track '19 Abelow the table'G,the operator moves the lever 1S to vrevolve the crankl in its mountingso that'the Icross bar i14 is lowered and Ythe jtrack inclineddownwardly to the level of the track 19, permitting the table 6 to belrolled fromthe ti'ack to position beneath the table 6'; The'tr'ack10`is tlieirfaised lto normal horizontal position and locked by movingthe lever 18 back to seat against the supporting ar1n20.

After' the tabler of cleaned kand trimmed celery has been moved onto thetrack 10 into position for the workmen who do the gradingQthetable G israised onto the track 10/ to receive the` uncleaned product. `To raisethe lower table to the initial position, the operator moves the Vlever32 rear-V wardly to revolve the crank levers 25-25 in their mountingsand thereby raise the track 19 withthe table thereon between the trackrails S35-3;?, the Y latter xtilting outwardly f on the hinged mountingsto permitthepas# sage oi' thetable therebetween, but allingf ,v backtocatch ythe table as soon as it has been ,suiicrently raised.

Bv so constructing the tableand tracks, `it

willvbe seen that the work otcleaning and asserting may beycarried-onbyA separate groupsotl workmen without contusionfand without theirchanging positions, thereby greatly facilitating the work, moreover, the

, work may all be accomplished without sliding or moving the plants,along V.the table, and thereby eliminate all vfriction, which would beapt to cause bruising of the plants, Having tlnisdescribed my inventionwhat ,I claimfas new, thereinand desireto vsecure by Letters Patent, is:

1. A conveying and cleaning table com- `prising ,separate coextensivetrack sections,

tables movable on said sections, and means for interchanging the tableson the separate sections.

2. A conveying and `cleaning table comprising separateeoextensive andindepend-V en tly movable track sections, tables adapt-ed for support onthe track sections, and means for shifting the tables from Vone toanother yof said sections. i

3. A conveying and cleaning table comp rising a fra-me, upper andylower-,tracks mounted in said'frame, and means for moving said tablesalong said tracks to linterchange their positions thereon.

4. A conveying and cleaning table'fcomprising a frame, uppertracksections and a lowertrack, tables adapted for rolling on saidtraeks,' and means for moving oneot' theaipper track sections to`cooperativerelation with the lower ti'aclgior the purpos A conveyingand Cleaningtable comprising c oeXtensive track sections, one yielddvbien its able `vertically to permit passage of a table between itsrails from'beneath the track level, andanelevatorfor positioning a tableon the yieldable track. Y t G. A conveying and cleaning table com-,prising coextensive track sections, one yieldable vertically `to permitpassageoi ya table betweenits rails from beneaththe track ,level, anelevator for positioning a itableon the yieldable track, and means forconducting a table from the other track section to said elevator.

7. ln a conveyingl and cleaning table, a track comprising rails havinglongitudinal, pivotal mounting, a track normally coeXtensive with thefirst named tra-ck, and having 'transverse pivotal mounting, tablesmovable on said tracks, and an elevator for receiving a table from oneof the tracks and con- 10 ducting the same to the other track.

8. A conveying and cleaning table coniprising a frame, upper tracksections forming a continuous track longitudinally of said frame, alower track, tables movably mounted on said tracks, means for moving oneof the upper track sections to coperatlve relation with the lower track,andmeans for raising the lower track to cooperative relation with theupper track section, for the purpose set forth. In testimony whereof IaiX 1ny signature.
